Document Type and Number:
WIPO Patent Application WO/2017/181327
Kind Code:
A1
Abstract:
The present invention provides a channel access method, device, and system, said method comprising: according to obtained load rate change information, an AP sending a first message to each member STA in an STA group corresponding to a first STA, instructing each member STA to access a channel within a group SP allocated by the AP for the STA group corresponding to the first STA, the positions of each of the members of the STA group being adjacent; the first STA receiving allocation information of the group SP sent by the AP, then accessing the channel in the group SP according to the allocation information. In the technical solutions provided by the embodiments of the present invention, an AP directly allocates a long group SP for an STA group corresponding to a first STA, such that the first STA sends in real time all load data within the group SP and allocates, in a targeted manner, the remaining time to other members in the STA group; the real-time communications requirements of the first STA are satisfied, while the monitoring power-consumption of the other STAs outside of the STA group is reduced.
